If you cared to observe you could experience some of this overwhelming evidence for yourself. If you own a motor car, get it idling on level ground and make sure the handbrake is on and the gears are in neutral or park. Then walk around to the back of the car and gently feel in front of the exhaust. Don't get too close because not only is the exhaust gas polluting, it's also likely to be hot and possibly dirty as well. All of that gas is pouring into the atmosphere just like the filth from this.
Now multiply the filth coming out of your car's exhaust and the filth coming out of the power stations by the number of vehicles and power stations worldwide. This just might give you an idea of what we are doing to the Earth's one atmoshere.
Perhaps then you might think about the arrogance of people who assert the right to freely pour their filth into the world's atmosphere. You don't own the atmosphere pal and neither do I. Just because the carbon dioxide in all that exhaust is invisible doesn't mean its safe. Just because carbon dioxide is food for plants doesn't mean plants can deal with excess.
Some people deny the science of anthropogenic climate change.
Some of these people are arrogant, some are fools, some are arrogant fools.
